Rise of pairwise thermal entanglement for an alternating Ising and Heisenberg spin chain in an arbitrarily oriented magnetic field
M. Rojas, S. M. de Souza, Onofre Rojas
Typically two particles (spins) could be maximally entangled at zero temperature, and for a certain temperature the phenomenon of entanglement vanishes at the threshold temperature…

Thermal entanglement in exactly solvable Ising-XXZ diamond chain structure
Onofre Rojas, M Rojas, N. S. Ananikian +1
Most quantum entanglement investigations are focused on two qubits or some finite (small) chain structure, since the infinite chain structure is a considerably cumbersome task. The…
